ABSTRACT:
A nozzle assembly (16), for spraying a liquid such as a urethane prepolymer on a substrate, has a liquid spray nozzle (28) with a center line (56). Air nozzles (30), with center lines (62) that are substantially parallel to the center line (56) of the liquid spray nozzle (28), are provided in the nozzle assembly (16) around the liquid spray nozzle. Air passing from the air nozzles (30) surrounds and encloses the liquid spray and decreases the size of the liquid spray fan pattern (58 or 70). The air spray nozzles (30) can be positioned in the nozzle assembly (16) to change the shape of the liquid spray fan pattern (58 or 70) as well as the size. Mixing of air and liquid is minimized by spraying air and liquid in parallel paths.
